MUSICALJNSTR-UMENT SPUR.

Application filed January 21, 1927, Serial No. 162, 13, and in. Germany September 20, 1926.

This invention relates to an improved spur used as a ground support for musical instruments of a certain character as, for example, cellos, base viols, and the like.

The main object of the present invention is to provide a spur of hollow form having open communication with the body oi the instrument to thereby increase and improve the resonance of the instrument.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a view in vertical section. showing the spur of the present invention in its preferred form.

Figure 2 is a similar View of a modified form.

The body of the instrument indicated at c is provided with the usual plug a, and the. outer end of the latter is recessed to receive the spur stem 6. The stem is hollow throughout, and the plug'is formed with a bore in line with the bore of the stem to provide an uninterri'ipted channel throughout.

The lower portion or" the channel is lined with a metallic piping c, which may be of brass or the like, the lower end of which is fitted to removably receive a point f, which may be frictionally or otherwise secured within the lower end of the piping c, and which, as shown more particularly in Figure 2, may be cored for the greater portion of its length.

In the preferred form, the upper portion of the bore formed throuh the stem and plug is interiorly fitted with a piping (Z which extends slightly above the inner end of the. plug within the body of the instrument and has its lower end of somewhat conical form to lit within the upper end of the upper piping c.

In the modified form, the parts as described in connection with the preferred form except in the particular form of the piping. In this instance, the piping is in the form or a single length of piping 9 formed at the. lower end to receive the point f of the preferred form and extending at the upper end into the body of the instrument at the upper end of the plug.

In the use of a spur of this type wherein a hollow lined space is provided, the resonance of the instrument proper is materially increased and is particularly not dampened by the usual solid spur bearing on the ground or other surface. It is of course to be understood that the function or the lining of the hollow spur is to amplify and increase the tone of the instrument, thus materially improving the resonant qualities of the instrument., and in order to provide the result the lining of the hollow spur is to be of a material which will participate in the vibrations of the instrument. Aside from this requirement the lining of the hollow spur may be of any appropriate material which will measureup to the stated purposes.

lVhat I claim as new is 1. A hollow supporting spur for bowplayed stringed musical instruments having a removable lining capable of participating in the vibrations of the instrument and open to the sound space of the instrument.

2. A hollow supportin spur for bowplayed stringed musical instruments, a lining therein, and a ground engaging point rcmovably seated in one end of the resonant responding lining, said hollow spur being open to the sound space of the instrument.

A hollow supporting spur lor bowplayed stringed musical instruments, a lining therein, and a hollow ground engaging point removably seated in one end of the resonant responding lining, said hollow spur being open to the. sound space of the instrument.

A. A hollow supporting spur for bowplayed stringed musical instruments, a resonant responding piping arranged therein for a portion of the length of the spur, and a second piping arranged throughout the remaining length of the spur, said hollow spur being open to the sound space of the instrument.

5. A hollow supporting spur for bowplayed stringed musical instruments, a resonant responding piping arranged therein for a portion of the length of the spur, and a second piping arranged throughout the remaining length of the spur, the meeting ends of the pipings interfitting frictionally, said hollow spur being open to the sound space of the instrument.

In testimony whereof I affix my signature.
